I have an old machine here that runs scandisk every time it boots up and then wants to carry out a surface scan too. When you let it do a scan it never finds any bad sectors. Occasionally it will thro up a message about not being able to write to the c: drive, sometimes on shutdown. If you hit exit at the start of scandisk it will happily go into windows and seems to run fine. The machine is running windows 98SE and the hard drive is on an IDE card because I had to fit a larger drive and the BIOS did not support large drives. The machine has been running fine for maybe 6 months since I changed the drive but now it has this problem. I did wonder if the drive may be failing, had it found bad sectors I would say yes but as it never does I am not so sure. Does anyone have any suggestions?
